Earlier this week, Jamba Juice released a new smoothie called Poolside Fit. In it, you’ll find familiar flavors — watermelon, cucumber, lemon, strawberry and peach — alongside an ingredient more commonly found in beauty products: collagen.
Collagen is a protein that’s naturally produced by the body. When production slows, which it does starting at age 20, wrinkles, sagging skin and joint pain creep in, Joel Schlessinger, MD, a Nebraska-based dermatologist and contributor to RealSelf, told Fox News.
To make up for that slowing production, many people apply collagen topically in the form of moisturizers and creams, and, increasingly, they are drinking a powdered version of collagen, which is easy to add to everything from smoothies to coffee thanks to its neutral taste.
